And the effects of effectively protecting the lead-acid battery main body, avoiding explosion and having excellent explosion-proof performance are achieved.

Description

technical field [0001] The invention belongs to the field of batteries, and in particular relates to a multifunctional lead-acid battery with an explosion-proof structure. Background technique [0002] Lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and its oxides. The electrolyte is a sulfuric acid solution. The main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. When discharging, the main components of the positive and negative electrodes are converted into lead sulfate; when charging, the main components of the positive electrode are converted from lead sulfate to lead dioxide, and the main components of the negative electrode are converted from lead sulfate to lead. The nominal voltage of a single-cell lead-acid battery is 2.0V, which can be discharged to 1.5V and charged to 2.4V; in applications, six single-cell lead-acid batteries are often connected in series to form a nomin...
